AdoptOpenJDK.net and OpenJ9

IBM folks were presenting a lot of OpenJ9 talks (their own OpenJDK build) available at adoptopenjdk.net (where you can download many types of OpenJDK builds for different architectures and OSes) and on DockerHub as well– OpenJ9 was built with mobile in mind but should be a good match for cloud workloads since it’s focused on rapid startup time, small memory footprint, and it can also use a networked JIT server to further accelerate startup times

Istio and tracing with Jaeger / Zipkin

Many speakers were talking about Istio and how it enables inter process tracing and canary deployments, etc. (see this demo repo from Redhat)

It’s interesting to see how with just some « istiofi’ed » kubernetes manifest files you get such interesting features « for free »; next step would be to also put some tracing spans intra VM (some spring boot plugins : spring cloud sleuth and java-spring-cloud, seem to give that automatically)
